Improving water productivity for various types of plants in different regimes of Iraq

Subsurface soil water retention technology is a modern tool to increase the yield and improved saving. The goal of this paper review gathered three selected local experimental woks carried out in different regimes Iraq purposes improving productivity for strategy plants some vegetables crops irrigated by utilizing irrigation systems installing membrane trough. Moreover, retained rainfall was also considered work. first work conducted open field, within Joeybeh Township, located east Ramadi City, Anbar Province, growing season winter wheat 2018-2019. second at Hawr Rajab district Baghdad City. plots were inside greenhouse cultivated with cucumber plant 2017. Additionally, third north Babylon Province Sadat Al Hindiya Township. okra For whole studies, installed trough below surface, while other not. Irrigation scheduling followed as well field. Other depend mainly on rainfed, without following schedule. At harvest days end season, obtained results show that economic plot supplementary 16 % 46 comparing applying depends only rainfed. plant, tough subsurface trickle 150 more than 78 using surface irrigation. gave 170 irrigation, respectively. crop highly trough, techniques schedules process avoiding stress much possible.
